WEST VIRGINIA, ASSIGNORS OF ONE-THIRD TO EUGENE VIRGINIA.

B. MILLER, OF KEYSER, WEST LOOK FOR SLIDING DOORS.

Application filed April 12, 1907.

To all whom it may concern:

Be it known that we, \VILLIAM F. BENTLEY and GEORGE W. OHnssHER, both citizens of the United States, residing, respectively, in the city of Baltimore and State of Maryland, and Keyser, in the county of Mineral and State of IVest Virginia, have invented certain new and useful Improvements in Looks for Sliding Doors, of which the following is a specification.

This invention relates to locks for sliding doors and has particular reference to car door locks.

One object of the invention is to provide an improved construction of lock of the character described by means of which the door will be held in close against the car body, and which will securely lock the door in the fully closed position or in a partially closed position for the purpose of ventilation.

Another object of the invention is to provide an improved hasp construction which may be turned in a vertical position and operated to lock the door in a closed position and also capable of movement to a horizontal position to lock the door partially closed.

Another object of the invention is to provide the hasp with a bolt device which may be reversibly mounted on the hasp so as to be moved therewith but which is also movable independently of the hasp.

Another object of the invention is to provide a hasp with two cross-slots one of which may be utilized to receive a staple to hold the door in one position and the other slot to re- I ceive a separate staple to hold the door in a different position and to mount a bolt on said hasp so it may be moved toward either of said slots to engage one or the other of said staples.

Other objects and advantages will become apparent from the description forming a part of this specification.

With these and other objects in view, the invention is illustrated in the accompanying drawings, in which,-

Figure 1, illustrates portions of the side of a car body and door and shows a side elevation of our improved lock devices attached thereto, but in the unlocked position. Fig. 2, illustrates a similar view,the said devices however being shown in the locked position. Fig. 3, shows a vertical section through the lock devices,the section being taken approximately on the line 3-3 Specification of Letters Patent.

Serial No. 367,866.

of Fig. 2. Fig. 4:, illustrates a plan View of the lock devices in the locked position,-the door and car body being shown in sections. Fig. 5, shows a front elevation of the lock, door and car body, the door being partially open and the hasp and locking bolt being turned in a horizontal position to engage and lock the door so as to permit ventilation, and Fig. 6, shows a plan view of the device in the position shown in Fig. 5.

Referring to the drawings, the numeral, 1,

j designates a portion of the car body wall and, 2, the door which may be mounted in any suitable or desired manner to slide in a longitudinal direction so as to close the side opening 3 of the car.

A bracket, 1, is secured to the wall of the car adjacent to the side opening and said bracket is provided at one edge with a wall, 5, which projects outwardly at right angles to the wall, 2, and forms a stop against which the vertical edge, 6, of the door may strike when the latter is being closed. laterally projecting flange or plate, 7, is provided at the outer edge of the wall, 5, and said flange projects over the outer surface of the door when the latter is fully l closed and serves to keep said door pressed 1 inwardly toward the side opening. The

' extreme vertical edge, 8, of the plate 7, is

j rounded or beveled so as to guide the door inwardly as the latter passes said edge.

Near its upper end the flange or plate, 7, is provided with a perforated lug or staple, 9, which projects outwardly in a horizontal plane from said plate and the bottom portion of said plate is provided with two outwardly projecting spaced apart ears, 10, with a ver-. tical slot, 11, formed in the plate between said two cars.

A bolt block, 12, is pivotally mounted between the ears, 10, of the plate, 7 and this block is provided at its lower end with a locking projection, 13, which projects through said slot, 11, and at the inner side of the plate 7. The upper exterior end of this bolt block is provided with a head, 14:, which has position on the exterior of the plate, 7 and a hasp plate, 15, is pivotally connected to said head so as to swing in a vertical 1 plane therewith or be turned laterally in a horizontal position with respect thereto. This hasp plate is provided with two crossslots, 16 and 17 which are spaced from each i other,said slots being located adjacent the able manner but said door is pushed oppositeends of the plate, and a slot, 18, extends longitudinally between said two cross-slots.

The position of the cross-slot, that when the hasp plate is in position it will receive the 111 9, on the .plate, 7, while the slot, vided for a scribed.

A securing bolt, 20 has a pin or rivet, 21, and this pin projects through the longitudinal slot, 18 in the hasp plate and has a head, 22 on its inner end which engages the inner surface of the hasp plate and holds the bolt loosely in position against the hasp. Ribs, 23, are provided at each side of the slot, 18, and on the inner surface of the hasp plate, so as to enable the head of the pin to slide longitudinally with respect to the hasp plate with freedom. By this construction it will be seen that the bolt, '20, is capable of both a longitudinal movement and a revoluble movement with respect to the hasp plate. The lower or engaging end of the bolt is provided at its front portion or surface with a slight cross-notch or recess, 24, for a purpose to be described and this same end of the bolt is also provided with slot, 25, through which the wire, 26, of the con- 'ventional seal, 27, may be passed after the bolt has been operated to engage a staple.

The plate, 7, is provided with a curved reinforce rib 28, which curves around the head, 14, and serves as a side stop for the head When lateral strains are applied thereto.

The locking projection, 13, has a beveled edge, 29, which serves as an entering wedge when the locking projection is engaged as will presently appear.

The door, 2, may be'of any preferred construction and hung so as to slide in any suitsaid door is provided with 30, which is bolted to its 16 is such a vertical or staple, 17 is propurpose presently to be dea locking plate,

outer vertical surface and said. plate is provided with a right angle extension or flange, 31, which extends cross-wise of the edge, 6, of the door. This plate, 30, is provided with a slot, 33, which extends vertically and ad jacent to and parallel with the vertical edge of the door as clearly seen in Figs. 1 and 5, of the drawing. In the present instance, the door itself is also provided with a vertical slot, 34, which registers with theslot in the plate, 30, as can be clearly seen in Fig. 3. A lug or staple, 35, is also provided on the door plate, 30, and this staple extends in a vertical direction and parallel with the slots in thedoor and plate.

It will be understood that the position of the plate 30, on the door is such that when laterally to close the opening in the car that the slot 33, and said door plate will project beneath the plate, 7, in the wall, 1, of the car so that the slots 33, 1' gaged with the locking said pivoted and 11, will be in register. When in this position the hasp plate, 15, will be swung upwardly and in making this movement the locking projection, 13, will project through the slots, 11 and 33, and enter the slot, 34, in the door as clearly seen in Fig. 3. Vhen in this position the staple, 9, will project through the slot, 16, in the hasp plate and the securing bolt, 20, may be turned so that its end may be passed through the hole in the staple, 9, and hold the hasp in the vertical position and thus retain the locking projection, 13, in said slots and hold the door closed.

I t is sometimes desirable during the transportation of a certain character of freight, such for example as vegetables or fruits, that the door should remain partly open for the purpose of ventilation, and we have provided 'a construction whereby this may be done and still be able to utilize our lock to hold the door in sition.

By reference to Figs. 5 and 6, it will belseen that the hasp plate, 15, being pivoted to the head, 14, may be turned from a vertical to a horizontal position and when in such latter position the cross-slot, 17, will receive the staple, 35, on the door plate. The securing bolt, 20, may then be revolved or partlyso,

such partly'open pcwith respect to the hasp p'lateso that its end may be passed through the staple 35, to lock the hasp plate to the latter. When the bolt, 20, has been passed through the staple, the slight crossnotch or recess, 24, will have such position with respect to the staple as to form a shoulder at each side thereof and prevent the bolt from accidentally working out.

lVhen the hasp plate is in the horizontal position, the rib or stop, 28, will serve to backup the head, 14L,and relievethe latter of side strains. 7

Having thus described our invention what we claim as new and desire to-secure by Letters Patent is,-

1. In a lock for tion with the stop plate having a staple, of a locking projection pivotally mounted "to the stopplate; a locking plate on the door with which said pivoted locking projection en gages; a hasp plate connected with the pivoted locking projection and having a slot to receive the staple on the-stop plate,-and a bolt carried by the hasp plate for-engaging said staple on the stop plate.

2. In a lock for sliding doors the combina- ,1

tion with the stop plate, of a locking tion pivotally mounted to the stop hasp plate pivotally connected with the pivoted locking projection and capable of a lateral movement independently of said projection; a locking" plate on the door with which locking projection engages; means for engaging the hasp plate with the stop plate tohold the locking projection 'enplate, and means to projecplate; a

improved slidingdoors the combinaengage the hasp plate with the locking plate when the hasp plate is turned laterall 3. In a lock for sliding doors the combination with the stop plate having a staple, of a locking plate on the door and also having a staple; a locking projection pivotally attached to the stop plate; a hasp pivotally connected to said projection and having two cross slots; and a bolt carried by and pivotally mounted on the hasp plate between said two cross slots.

4. In a lock for sliding doors the combination with the stop plate having a staple and a vertical slot, of a locking plate also having a staple and a vertical slot,-the staples on the two plates extending at right angles with respect to each other; a locking projection movably attached to the stop plate to enter the slots in the stop and looking plates when said slots are in register; a hasp pivoted with respect to the stop plate and having two cross slots, and a bolt slidably and pivotally mounted on the hasp plate and movable longitudinally on said plate between the two slots thereof.

In testimony whereof we aflix our signatures in presence of two witnesses.
